And one look at the record shows that Perry will find a warm reception for his comments among many congressional Republicans, who have tried for years to fundamentally change the program. Just this past June, House Republicans introduced a measure to privatize the program, potentially turning over Americans’ retirement security to the whims of the stock market.

Rep. Jeb Hensarling on Social Security, Medicare and Medicaid: “Let’s remember again the main drivers of this national debt are three large entitlement programs, programs that have been of great comfort and assistance to my parents and grandparents but they’re morphing into cruel ponzi schemes for my 9-year-old daughter and 7-year-olds.” [4.16.11]

Sen. John McCain on Social Security: “It’s a Ponzi scheme that Bernie Madoff would be proud of.” [2.22.11]

Democrats are committed to preserving and protecting this bedrock program and welcome a debate on the merits of its very existence.
